What is the difference between a food chain and a food web? When you eat a hamburger what trophic level are you eating at? How much energy do you get at each trophic level? Are humans producer s or consumers? What percent of the suns energy are you getting when you eat a hamburger? a salad? Create a food chain containing grass, a grasshopper, a frog, a snake, and an owl. Show the energy pyramid that it would create. http://videos.howstuffworks.com/planet-green/30304-g-word-red-wigglers-video.htm Earthworms: 1. What is a hemaphrodite? Why is this important for an earthworm? 2. How does an earthworm move? 3. What is a decomposer?
Overall Expectations By the end of this course, students will: • demonstrate an understanding of the dynamic nature of ecosystems, including the relationship between ecological balance and the sustainability of life; • investigate factors that affect ecological systems and the consequences of changes in these factors; • analyse issues related to environmental sustainability and the impact of technology on ecosystems.
Examine the graphs created in class. What factors caused the population changes between the following:
between years 1 and 2
between the years 4 and 5
between the years 7 and 8
between the years 10 and 11
4. Is there ever a balance achieved in nature? Explain
5. Name an example of a predator and prey relationship
6. Does the predator or prey have more of an influence on the control of the population?
7. What are 3 examples of other limiting factors that could influence the populations of deer or wolves? http://www.youtube.com/watch?v=TE6wqG4nb3M
